Abstract
There is provided a rotation detection jig used for an apparatus in which a substrate is processed inside a processing container by rotating a mounting stand for a substrate provided on one surface side of a rotary table while revolving the mounting stand with rotation of the rotary table, and supplying a processing gas to a region through which the mounting stand passes, including: a rotating element configured to rotate about a rotation shaft of the mounting stand; an encoder main body configured to detect a rotation angle of the rotating element and configured to constitute a rotary encoder together with the rotating element; a fixing member configured to fix the encoder main body to a rotating portion including the rotary table; and a signal processing part provided in the rotating portion and configured to process a detection signal detected by the encoder main body.
